Windows 10: How to change app data to another folder/drive

Hello MS I am Abikrishna a MS userI want to change my app data to another drive without making any files damage.my drive is almost full and get lagging. Hope you help me. Kindly Abi

Upgrading my data drive HDD

I am not the one actually set it up for me I had geek squad do it for me because I didn't want to mess it up. but the folders that are listed in the data drive is
program data
steam
users
windows apps
razar soft wear

 

Split Steam app folder between 2 HDD?

As the title suggests I want to find out if there's a way I can split my steam app folder on to 2 drives, specifically an SSD that I will be putting my OS and most used games and apps and a regular HDD for everything else?

 

Directing data to a second drive ?

To direct data to a second drive I thought you opened File Explorer > This PC > then right clicked (for example) Music > Properties and changed the Location.

However I can also open File Explorer > This PC > then left click Documents which displays Music along with other the folders.
1) If I right click the Documents folder & change the Location, will that also change the Music & other folders listed within Documents?
2) Why are the Music & other folders listed in Documents when they are already listed under This PC?
File Explorer also shows Music under Quick Access. That’s 3 occurrences I’m looking at. Does it make a difference which one I use to change the Location?

Recently I came across this method which looks like it does the same thing, but does it?
How to Change the Default Hard Drive for Saving Documents and Apps in Windows 10

Some online comments suggested creating a separate folder for each user account and make the new folders as subfolders of the user account folder. I am the only user. Is there some advantage of creating a user folder?

I've never used a second drive for storage & any suggestions would be appreciated.
Thanks
